ABSTRACT
OBJECTIVE@#To investigate clinical effect of partly weight-bearing walking and functional exercise immediatly after operation for Achilles tendon rupture(ATR) on function of ankle joint and rate of fragmentation of Achilles tendon, through comparing effect of partly weight-bearing walking and functional exercise immediatly at 2 weeks after operation for Achilles tendon rupture.@*METHODS@#Sixty-four patients with ATR selected from March 2012 to March 2013 were randomly divided into two groups. There were 34 patients in treatment group, including 18 males and 16 females with an average age of 41.4±7.6, they began to do functional exercise and walk on fields with partly weight-bearing at two days after operation; there were 30 patients in control group, including 16 males and 14 females with an average age of 39.9±7.6, and they were immobilized with plaster in plantar flexion at two weeks after operation, and started to do functional exercise and walk on fields with partly weight-bearing at two weeks after operation. Two groups were performed by the same doctor with the same operation. The rate of fragmentation of Achilles tendon, and AOFAS score and complications between two groups were observed and compared.@*RESULTS@#AOFAS score in treatment group at two weeks after operation was 74.3±3.9, which in control group was 71.7±4.2, and had statistical differences between two groups; AOFAS score in treatment group at one year after operation was 93.3±3.9, which in control group was 92.0±4.1, and had no statistical significance. No Achilles tendon fragmentation in treatment group occurred at three years after operation, and 1 patient occurred in control group. Two patients in treatment group occurred complications after operation, and 1 patient occurred in control group, however, there was no statistical significance between two groups.@*CONCLUSIONS@#Functional exercise immediate after operation for Achilles tendon rupture(ATR) patients in the early days, the AOFAS scores is higher than the fixing for two weeks, and does not increase the rate of fragmentation of Achilles tendon and complication after operation, and benefits for function recovery.

<p><b>OBJECTIVE</b>To analyze the characteristic of the radioactive lymph node with metastatic disease and to explore the method of the localization of sentinel lymph node (SLN) with radionuclide in N0 clinically laryngeal and hypopharyngeal cancer.</p><p><b>METHODS</b>Fourty-five patients with T1-T4 and clinically N0 laryngeal and hypopharyngeal cancer were recruited. For each patient a peritumoral submucosal injection of 99mTc-labeled sulfur colloid (99mTc-SC) was performed and lymph node mapping was performed by lymphoscintigraphy two hours afterward. The SLN was localized by a handheld gamma probe intraoperatively 10-12 hours after the injection. All hot lymph nodes accumulating activity were harvested and initially termed sentinel nodes. Selective neck dissections were performed for all patients. The specimen of SLN was sent to the pathologist for the following analysis: formal paraffin embedded section, consecutive section and immunohistochemistry assay. The results was compared to the remaining lymphadenectomy specimen. Resection of the primary tumour depended on the location and the T classification.</p><p><b>RESULTS</b>SLNs were identified in 41 of 45 patients with 51 necks, SLNs had occult metastases in 13 cases, 15 necks with SLN-positive of these 13 cases, there was one false negative case, they were found in non-SLNs of neck specimens. Each neck side was considered a single case. SLN identification rate was 92.7%, sensitivity was 93.7%, false-negative rate was 6.3%, and accuracy was 98.0%. In 11 (73.3%) of these SLN-positive necks, the SLN with the highest counts contained tumor; harvesting the first-three nodes with the highest radioactive counts, which could all patients with occult metastatic disease.</p><p><b>CONCLUSIONS</b>Excision of the first-three SLNs with the highest radioactive counts can accurately judge the presence or absence of the cervical lymph nodes metastases in patients with the clinically N0 laryngeal and hypopharyngeal cancer.</p>
